  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x386cf24a1b548207b900b34cc5dd2a2babc94550719779ec2deb5e58fba46052. Chain 2 (Bitcoin): anchored in block 953536 (2026-06-13T17:25:41Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/0LvG3UXNhrQe0yyUjqlQGo.json contains the same CopyrightID — hash it and compare to OTSHash, then confirm the Bitcoin block independently via OTSBitcoinBlockVerifyURL or https://artists.proofprofile.net/api/v1/bot/ots/verify/track/0LvG3UXNhrQe0yyUjqlQGo.
